When plants are exposed to too much light, the excess energy overwhelms the plant’s photosynthetic apparatus. The light-absorbing pigment chlorophyll gets damaged, leading to decreased photosynthesis, and plants tend to damage cells. This form of light stress is particularly prevalent in indoor gard...
These include the time of the day, season, geographic location, atmospheric gases and moisture, clouds, smoke, dust, and other pollutants in the air, topography, presence of barriers including other plants, plant architecture, and location of absorbing plant organs within the canopy. Thevisible wa...
By contrast a dominant aurea mutant in tobacco, Su/su, which was discovered by Burk and Menser in 1964 [2], requires high light intensities for normal growth. The mutation has apparently produced a sun plant in which the inherited loss of light-absorbing pigments has been made up by an ...
The far-red absorbing pigment, P700, is considered to be a crystallized chlorophyll that may participate in photosynthetic energy collection but is not essential for the overall process. The model is tested by comparisons with experimental evidence from fluorescence, afterglow, the Emerson effect, ...
As soon seedlings are exposed to light, fully functional chloroplasts develop, enabling photosynthesis to take place in reactions dependent on light-absorbing pigment molecules present in the thylakoids. Here, light energy is converted to chemical energy, which involves a series of chemical reactions ...

Universal cyanobacterial phycobilines are the blue-colored allophycocyanin (absorbing maximally at a wavelength of 650 nm) and phycocyanin (maximum at 620 nm). Phycoerythrocyanin (maximum at 575 nm) and the red-colored phycoerythrin(s) (maxima vary from 495 to 560 nm) are also common. ...
From the viewpoint of light-harvesting, in most organisms carotenoids are accessory pigments absorbing in the blue-green region of the solar spectrum, where chlorophylls and bacteriochlorophylls have weak absorption. Here, we discuss carotenoid light-harvesting in a pigment-protein complex having ...
However, it has been found that the plant growth is selective in light absorption, mainly due to the differences in light absorption by four main pigments in plants (chlorophyll A, chlorophyll B, photosensitive pigment PR and photosensitive pigment PFR). Blue light (400–500 nm), red light (...
